WINDOW-SASI-I FASTENER.

Application filed November 7, 1925. Serial No. 67,607.

This invention relates to a window sash fastener, and has for its object to provide, in a manner as hereinafter set forth, a fastener of such class having means whereby the upper and lower sashes can be fastened in closed position, as well as in partially open position, relatively to each other, to allow for ventilation when desired.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a `window sash fastener which is simple in its construction and arrangement, strong, durable, thoroughly efficient and convenient in its use, readily installed and comparatively inexpensive to manufacture.

With the foregoing and other objects in View, the invention consists of the novel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is a fragmentary view of a window frame and a pair of saslies and further showing in side elevation a sash fastener, in accordance with this invention, in locking engagement.

Figure 2 is a like view wit-h the fastener in released position.

Figure 3 is a section on line 3 3, Figure 1.

Figure 4 is a section on line 4 4, Figure 3.

Figure 5.is a section on line 5 5, Figure 4. l

Referring to the drawings in detail, 1 denotes the front, 2 the back and 3 one side of a window casing or frame, and 4, 5 and 6 the beads of the frame and between which the upper sash 7 and lower sash 8 slide. The lower rail 9 of the sash 7 has its rear side bevelled, as at 10, and the upper rail 11 of the sash 8 has its forward side bevelled, as at 12, whereby when the sashes are in closed position, the rails 9 and 11 will abut in the manner as shown to form a tight joint.

One of the side rails, as indicated at 13, of the upper sash is formed directly above the rail 9, with a vertically extending groovelat in the rear face thereof, and the Vportions 30 and 31.

rail 11 has its forward face, at one end, formed with a vertical groove 15. Secured in the groove 14, by the hold-fastV devices 16, is a toothed bar 17, which provides what may be termed a ratchet strip.

Seated on the rail 11, at one end thereof, is a vertically disposed supporting member consisting of a base 18 formed with a pair of oppositely extending laterally disposed apertured iianges 19. Integral with the lbase 18 is a pair of spaced vertically disposed opposed arms 20, 21, each having an opening 22 near its upper end centrally thereof. Depending from the base 18 and the inner portion of each of said flanges is a rectangular extension 23, formed with an opening 24. The upperface .of the base 18, in proximity to its forward end is pro vided with a socket 25. Y

The base 18, is seated on the rail 11 and secured therewith by the hold-fast devices 26 extending through the flanges 19 and engaging in said rail. The extension 23 snugly iits the groove and is secured to the rail 11 by the holdfast device 27 extending through the opening 24 and engaging in said rail. 1

Secured in the openings 22 is a pin 28, upon which is pivotally mounted a locking lever 29 formed of a substantially elongated rear or handle portionl 39, an intermediate portion 31 of greater width and of less length than the handle portion 30, and a. segment shaped forward portion 32 having a toothed forward edge 33 to engage the toothed bar 17 to lock the sashes together. The forward portion 32 is of a width less than the length of the portion 31, and of a length greater thanthe width of the portion 31 and of greaterthickness than the The portion 31, `between its vertical center and rear end, is

fformed with an opening 34 for pivotally mounting the lever 29 on the pin 28. The

lower edge of the lever 29, at the point of ioinder between the portions and 31 is provided with a socket 35, which is positioned rearwardly with respect to the socket 25. The socket 35 extends rearward ly at an upward inclination, and the socket 25 is vertically disposed. Mounted in the socket 25 is the lower end of an upwardly extending and rearwardly curved coiled controlli .fig spring 36, which has its upper end seated in the socket 35.

Protally' connected to the arno; 21,10@

low the pin 28 and in proximity to the rear edge ofsaid arm is a spring controlled latching lever 87 for maintaining the locking lever in inoperative position or with the toothed end of the locking lever clear ot the toothed bar 17. rlhe lever 37 is of curved contour and has its forward end provided with an opening 38 for pivot-ally n'iounting it on al pin 39, which projects from the outer side of the arm 21 and is positioned below the pin 28 and in proximity to the rear edge of the arm 2l. The forward end of the lower S7 has projecting therefrom a hook-shaped extension t0, which is of inverted V shape, and the free or forward arm of said extension Ll is connected, as at eti to the upper end of a controlling spring` 42 therefor, and said spring has its lower end anchored to one of the flanges 19. lThe rear end of the latching lever 37 is formed with an opening i3 for the purpose of connecting a pull member lll therewith. The lever 37, between its vertical center and its forward end has projecting from its upper edge vert'cally disposed hook 45, adapted to engage over a laterally extending stud 46, carried by the locking lever 29, for the purpose of maintaining the latter free of the toothed bar 17, in a manner as shown in Figure 2.

ln the operation of the device, should it be desired to raise the lower sash or lower the upper sash, the handle portion of the locking lever 29 is pulled downwardly until the vhook l5 overlaps the stud 46, as shown in Figure 2, whereby the teeth 33 are moved out of engagement with the teeth of the bar i7, thus releasing the sashes. Should it be desired to fasten the sashes in any position required, the member 44 is pulled downwardly releasing the hook 415 from engagement with the stud i6 and the teeth 38 will automatically engage with the teeth of the bar 17 thus fastening the sashes owing to the action of the spring 36.

it. is thought that the many advantages of a window sash fastener, in accordance with this invention, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet changes in the details of construction can be had which will fall within the scope of the invention as claimed.
